right click for circles, and right click and move de mouse for the arrows

You can draw arrows (only visible for yourself) on the board during the game or during training. You can draw an arrow by holding the mouse button and right click from square A to B. Different colours are achievable when holding Alt (blue), Shift (Red), Alt+Shift (Gold).
